Abstract:
Objective To evaluate fluid responsiveness by stroke volume variation (SVV) in mechanically ventilated patients with refractory septic shock.Methods Forty-two refractory septic shock patients were enrolled in the study.According to the responsiveness of fluid loading, the patients were divided into responsive group and non-responsive group.The SVV values of two groups were retrospectively analyzed.The receiver operating characteristic curve was drafted to determine the cut-off value of SVV for predicting fluid responsiveness.Results Among the 42 refractory septic shock patients, 24 were found responsive to fluid loading, 18 were not;before the fluid loading, central venous pressure, heart rate, mean arterial pressure and global end-diastolic volume index in the both groups showed no significant differences whereas the SVV in the responsive group was much higher than that in the nonresponsive group (P =0.006).Using SVV ≥ 12% as the threshold to predict fluid responsiveness, the sensitivity was 77%,specificity was 85%.Conclusion SVV can accurately predict fluid responsiveness in refractory septic shock patients.
